THERMOCOUPLE INPUTS AND CONFIGURATION JUMPER (JP5)

Although the Relay PCA supports two thermocouple inputs, these analyzers only utilize
one. It is used to sense the temperature of the Ozone Destruct.
• This single thermocouple input is plugged into the TC1 input (J15).
• TC2 (J16) is currently not used (see Figure 6-13 for location of J15 and J16).
The type and operating parameters of this thermocouple are set using a jumper plug
•
(JP5).
The default configuration for this thermocouple is:
Type-K
•
Temperature compensated for Type-K
•
Isolated

The PMT temperature is maintained by a separate control loop
that does not involve the relay PCA (see Section 6.5.2).
